Lecture Note 180
Numerical question:
A mass attached to a spring oscillates with simple harmonic
motion. The amplitude of the motion is 0.2 meters, and the angular frequency is
4 radians per second. Calculate the displacement of the mass at time t=1
second. Assume the mass starts from its equilibrium position (ϕ=0).
Review to learn updated information in regard to the national coordinate and reference systems
The meaning of the results output from web based GNSS processing
The coordinates and velocities of
ISTA point on 10.11.2016 are given to be
X = 4208830.2223 m, Y = 2334850.3312 m, Z = 4171267.3146 m and Vx = -0.0173 m/yr, Vy = 0.0150 m/yr, Vz = -
0.0093 m/yr respectively in ITRF2014. Transform these coordinates to ITRF96, 2005.0
to later on use them in detail measurements.

The mean anomaly (Mo) has been corrected in the "Given" section.
Notations in the numerical example have been revised and corrected.
The lecture note "Intro to time series analysis" has now been updated! The plot showing "local topocentric coordinate system" has been renewed for better comprehension.

The exam will be a multi-choice plus a conventional open-ended question (worthing about 20 pts). No cheat-sheet (a formulation page) is allowed!! You can bring your hand calculators. Good luck.
